Site Historv
There is an existing three-bedroom residence on the site that is served by an existing onsite wastewater
treatment system (OWTS) that is experiencing slow drainage and signs of failure. The owner ofthe property
wishes to replace it with a new OWTS sized to accommodate three bedrooms total.
The existing septic tank has been pumped several times and there is evidence of surface discharge indicating
that the soil treatment area (STA) has failed completely and is no longer accepting effluent. To expedite the
repair of this system, the following OWTS design has been completed using information gathered from the
OWTS Permits for the neighboring property at 4947 CR 346, Silt, CO 81652 (Garfield County Permit
Numbers 4636 and 4641, Appendix A), as well as the USGS Web Soil Survey (Appendix B). A soils
observation trench must be excavated within 50' of the nronosed STA and the design ensineer
notified for an onsite evaluation nrior to install. If site conditions differ from those assumed. a
redesign mav be necessary.
Development of Design Parameters
As mentioned above, this design has been prepared using information gathered from the OWTS Permit for
the neighboring property at 4941CR 346, Silt, CO 81652 as well as the USGS Web Soil Survey. The soils
evaluation and perc test performed by Hepworth-Pawlak Geotechnical, Inc., and described in the report
titled "Subsoil Study for Foundation Design & Percolation Test, Proposed Commercial Building, 4941
County Road 346 (Mamm Creek Road), Garfield County, Colorado" indicates that the native soils consist
mainly of sandy silty clays, with perc rates ranging from 90 minutes per inch to 180 minutes per inch. No
groundwater was encountered at the time of the test, however the engineered design of the neighboring
OWTS prepared by All Service Septic on May 5,2009 was designed assuming that there was shallow
groundwater.
The USGS Web Soils Survey indicates that the area of the proposed repair STA consists mainly of Heldt
clay loam with I to 3 percent slopes.
Based on the information gathered, Soil Type 4 and corresponding long term acceptance rate (LTAR) of
0.30 (TL3) are chosen for overall system sizing of a pressurized mounded soil treatment area (STA)
designed to discharge to subsoils below the 36" depth is proposed for this project. UPON ONSITE
EVALUATION, SHOULD THE SOIL TYPE/GROUNDWATER DIFFER FROM WHAT HAS
BEEN ASSUMED, A MODIFICATION OF THIS DESIGN MAY BE NECESSARY.
System Desisn
A pressurized mound soil treatment area (STA) is proposed for discharge of septic effluent at the site. The
STA will consist of one bed as shown in the included graphics. Construction of the system will consist of
removing the native soils from the area underlying the bed of the proposed STA. The initial excavation
will be continued to a level base at a depth of 36" BGS (see Soil Treatment Area Cross Section).
Following completion of the initial push out, the open excavation will be backfilled with 36" (min. depth)
ofASTM 33 concrete sand (secondary sand) to a surface elevation of0" above ground surface. A gradation
analysis done within 30 days of the installation date must be submitted to the design engineer and Mesa
County to assure the sand conforms to secondary sand standards (Mesa County OWTS Regulations
43.11.C.d.3; effective size: 0.15-0.60 mm, uniformity coefficient: < 7.0, percentage fines passing #200
sieve: < 3.0). The sand used must be completely settled prior to installation of components as approved by
the design engineer.
Following installation of the mound, QUICK4 STANDARD INFILTRATORS (or equivalent) will be used
to construct a septic effluent distribution system in the open excavation. The INFILTRAZOR effluent
distribution system will be installed in accordance with the "Infiltrator Technical Manual", available from
Infiltrator Systems Inc., 123 Elm Street, Suite 12, Old Saybrook, Connecticut 06475. Adiacent
INFIZZRI ZORS shall be fastened with a minimum of three (3) %" self-tapping screws to prevent movement
and separation during backfilling.
After the INFILTRATORS are installed, synthetic filter fabric (140-200 mesh) will be placed over the
INFILTRATORS and the system will be covered with a soil cap. The soil cap will consist of approximately
18" of sandy loam soil mounded 50% to promote surface run off away from the soil treatment area. The top
of the cap will extend above the existing ground surface. Extension of the cap side slopes from the cap
perimeter to the existing ground surface shall consist of:
1 . Maintaining a slope no steeper than 3H:1V from the cap perimeter to the existing ground surface,
and
2. Scarifying the native soil surface under the cap sidewalls to promote subsurface absorption.
All required setbacks shall be taken from the edee ofthe sand bed.
Septic effluent will be introduced into the soil treatment area through pressurized distribution laterals
installed in each row of INFILTRATORS as shown in the included graphics. The injection laterals will
consist of 7-Vq" Schd 40 PVC pipe with 5132" holes equally spaced 48" o.c. along each row of
INFILTRATORS. Holes in the injection laterals will be drilled aI L2:00 o'clock to direct effluent up for
dispersal against the top of the chamber. Injection laterals shall be suspended from the top of the chamber
with all-weather plastic pipe strapping (min. 120 lbs tensile strength) at every chamber joint connection.
There is an existing, 1,000 gallon, two compartment septic tank on site that may continue to be used once
it has been inspected and found to be in good working order. The existing tank is large enough to provide
a minimum of 48 hours retention time for sewage generated from the proposed project. If the existing septic
tank is not found to be in good working order, it must be abandoned in place or removed. Abandonment
shall consist of pumping the tank of all solids prior to being crushed. All void space must then be filled with
gravel, sand, or compacted soil.
a
A 300-gallon minimum, single compartment pump chamber will be placed down-gradient of the 1,000-
gallon tank. A screened effluent pump will be placed in the pump chamber. The effluent pump system will
employ an OSI high head, non-clog (3/4" solids handling capability), effluent pump (OSI model no.
PF500511) and screened pumping vault (OSI model no. PVU57-1819-L).
A 2" Schd 40 PVC pressure transport line will be used to transfer septic effluent from the pumping system
to the STA. The pressure main will be self-draining or be buried a minimum of 36" below ground surface
to prevent freezing. All pressure piping and construction shall be completed in accordance with the attached
graphics.
As shown in the attached graphics, the soil treatment area will consist of one bed 12'x125' in lateral
dimensions and encompass a total area of 1,500 sq. ft.

The syslem confractor shall he aware of the potential for constnrction activities to reduce soil
permeabilities at the site through compaction, smearing, and shearing. The following
precautions and construction procedures should be employed during installation to minimize
disturbance to native soils:
i. Excavation should proceed only when the moisture content of the soil is below the
plastic limit. If a sample of soil forms a rope instead of crumbling when rolled
between the hands it is too wet and should be allowed to dry before excavation
continues.
ii. Excavation and backfill equipment should work from the surface where at all
practical to avoid compaction of the soils at depth.
iii. The bottom and sidewalls of the excavation should be left with a rough, open
surface. The appearance should be that of broken or ripped soil as opposed to a
sheared, smeared, or troweled surface. Any smoothed or smeared surfaces should
be removed with a toothed rake or shallow ripper taking care to remove loose
residues from the bottom of the excavation by hand if ncccssary.
iv. Care should be taken in placing fill materials in the excavation to avoid damaging
the exposed soil surfaces.

Operation - Maintenance and lnspections
The owner shall install a structural barrier if necessary and take precautions to prevent vehicular
traffic, excessive surface watering, accidental flooding, or other activities in the vicinity of the
soil treatment area which may compact, saturate, or otherwise alter the subsurface soil
parameters used in designing the septic system.
The owner will plant and maintain grass or other shallow rooted cover crop to prevent erosion
and promote evapotranspiration over the soil treatment area.
The owner will inspect and maintain the required mounding and drainage away from the soil
treatment area to prevent saturation from precipitation and surface flows.
To mitigate the generation of preferential flow channels which may compromise the operation
of the system, the owner will inspect and prevent intrusion of burrowing animals and deep-
rooted plants into the soil treatment area.
The septic effluent pump and the effluent pump filter shall be inspected and cleaned as
necessary every six (6) months.
The owner will conduct periodic maintenance of the septic system by removing accumulated
sludge from the septic tank every 3-4 years to prevent clogging ofthe soil treatment area.

NOTES FOR YOT]R INSTALLER
Please veriry slope at the time of system installation - the orientation of the
STA shown in this design has been determined based on existing site
conditions at the time of the original site investigation, but that may have
changed during construction and pre-construction grading of the site.
The depth of the trenches is determined by percolation rates and soil
conditions relative to the existing ground surface at the time of the soils
investigation. If the site slope or grading of the ground surface at the time of
installation differs significantly from what was initially observed, the trench
depths may have to be adjusted to make sure the infiltrative surface remains
in the desired soil layer, and portions of the trenches don't end up too deep or
too shallow. The depth of the soil cap relative to finished sradins is not oart
of the OWTS isn criteria.
o Please provide K-Cronk Engineering with a copy of the septic tank
manufacturer's specification sheet veriffing maximum backfill depth. Tanks
must be backfilled according to manufacturer's specification.
Pressurized System Notes
r Please provide K-Cronk Engineering a copy of the sand sieve analysis, if
relevant, dated within 30 DAYS of installation before purchasing/installing
the sand so we can check that it meets Garfield County OWTS standards.
r Pump floats do not come pre-set from the factory. Please refer to the Pump
Vault Detail for the distance needed between the on/off floats.
Please reach out at any time during the installation process ifyou have any questions!

Repair Onsite Wastewater System Design,Z-Bedroom Residence and Employee Bathroom
4941F County Road 346
Garfield County, Colorado
Bruce,
ALL SERVICE septic, LLC prepared a repair onsite wastewater system (OWS) design for the subject
property. The property is located outside of Silt, in an area where OWS and wells are necessary.
SITE CONDITIONS
A 2-bedroom modular house zurd a warehouse with one bathroom exist on the subject property. They
currently utilize an OWS which is experiencing problems. The existing $eptic tank is in fair condition
and may be used, although the existing drain field will have to be replaced. The existing warehouse
has two full-time employees and five parttime employees. The proposed drain field mound area lies
north of the modular house. Vegetatiou consists of a moderate cover of native grasses. Water will be
provided by the onsite well, as indicated on Figure 1.
SUBSURFACE
The subsurface was reported by HP Geotech (project no 105 866) and by Garfield County (permit
#1049). The materials encountered consist of moist sandy clay. Groundwater or bedrock was not
reported by HP Geotech although we are designing OWS based on high groundwater. A 90 MPI rate
will be used to design the OWS.
DESIGN SPECIFICATIONS
The OWS design is based on 2-bedrooms and ? employees, and an average sewage load of 395 GPD.
I'he installation must include the existing 1000-gallon, two-compartment, precast concrete septic
tank, with arr effiuent filter to be added on the outlet, One 'Quick-4' gravelless chamber bed must be
installed as indicated on attached figures. 96 chambers must be installed to distribute effluent to the
raised bed. The total basal area is 1225 SF. Imported filter material must be used to construct
ulderlying bed. The filter material per the site visit on April 22nd, which was a clayey organic sand,
may be used. A levsl manifold and perforated PVC laterals must be installed to distribute effluent.
onsite wastewatef systern
Page2
The filter material must be compacted well to minimize any risk of settling when introducing
effluent. Differential settlement may occur if compaction is not adequate.
Construction must be according to the Garfield County Flealth Department OWS regulations, the OWS
Construction Permit provided by tlie county, and this design.
OPERATION INFORMATION AND MAINTENANCE
The sulface of the drain field should be seeded upon completion. Vegetation is an important factor in
drain field performance. Erosion control shouid be practiced prior to and during re-vegetation. Geo-
fabrics or plastics should not be used over the drain field. No heavy equipment, machineryo or
materials should be placed on backfilled drain field. Livestock should not graze on the drain fiekl.
Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWS.
For Example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and
harm a drain field.
The homeowner should pump the septic tank every two years and clean the effluent filter as needed,
Garbage disposal use should be minimized, and non-biodegradable materials should not be placed
into the OV/S. Grease shouid not be placed in househoid drains. Loading from a water softener
should not be discharged into the OWS. No haaardous waste$ should be directed into the OWS.
Mechanical room drains should not discharge into the OWS. The OWS is engineered for domestic
waste only.
ADDITIONAL CONSTRUCTION }.[OTES
If design includes a pump, air reiease valves and weep holes should be installed to allow pump lines
to drairr to minimize risk of freezing. Excavation equipment must not drive in excavation of drain
field due to the potential to compact soil. Extensions should be placed on all septic tank components
to allow access to them frotn existing grade, Precast concrete tanks and distribution boxes should be
used, unless plastic or fiberglass is tequired. Access to all tank compartments and distribution devices
is optimal.
TNSTALLATION OBSERVATIONS
ALL SERVICE septic, LLC, and the county must view the OWS during construction. The OWS
observation should be performed before backfill, after placement of chambers and distribution pipes.
Septic tanks, distribution deviceso pumps, dosing siphons, and other plumbing, as applicable, must

LIMITS:
The design is based on information submitted. If soil conditions encountered are diffferent from
conditions described in rsport, ALL SERVICE septic, LLC should be notified. Atl OWS consEuction
must be according to the county regulations. Requirements not specified in this report must follow
county regulations. The insaller should have documented and demonstrated knowledge of the
requirements and regulations of the county in which they are working.
Please call with questions.
Sincerely,

Subject:Subsoil Study for Foundation Design and Percolation Tesl proposed
Commercial Building,494l Counry Road 346 (Marnm Creek Road|
Garfield County, Colorado
Deu Mr. Collins
As reguested, Hepworth-Pawlak Geotechnical, lnc. performed a zubsoil study and
P€rcoJation test for foundation and scptic disposal designs at tbe zubject site. The srudy
was eiiiducted in acctirdilcc qith.orn agroemeot for gLtechnical engrueering services ro
you da,tei! Scptcurbii 28,'2005.'The data obtafued and o,.u recommendatious based on the
propoSed construction qnd zubsurface onditions escount€red are prescnted in this report.
Eval"iition of pote,ntial gbologic hazsrd impacts ou Ge site arebeyond the scope of this
study.
frop'i*eA Conitrii'ction: 'The
proposod building will be a single story steel frarne and
metal stnrctr:re located on the site as shown on Figpre l. The floor will be slab.on-grade
at an elevation of 5260,3 fest. Cut deptbs are expectd to range between ahout 2 to 4 feer
For.rndation loadings for this tlpe of constuction are assurned to be light to moderate anC
carried primarily by wideoed pad footings and typical of the proposed f,vpe of
construction. The serptic disposal system is proposed to be located east of the buildin_e.
If building conditions or foundation loadings are significantly differenr from those
described above, we should be notified to re-evaluate the recomrnendations presenteC in
this repon.
Site Conditions: The site is occupied by an existing modular residence and meral
building as shown on Figure L The terrain ransitions from a rnoderate (northwest
facing) slope jusr below county Road 346 to strongly sloping in the existing and
proposed development areas. The ground surface has undergone some grading consrsting
of apporent shrllow fill placcmcnt. Thcrc is about I foot elevation differcnce across the
nronosed buildins Vesetefion cnneiste af wpede with sraqs. in thp ditah aren alnna rhefl
south side of the property. The ditch wcs flowing warer at the time of our field
exploratiorr
Subsurfece Conditious: The subsurface conditions at the site were evaluared b,v
excavating two exploratory pits in the building area and one profile pit in the septie
disposal area at the approximate locations shown on Figwe l. The logs of rhe pirs are

'time of
Foundatioi the iub$oil coiittitions enount€rcd in the
exploratory pits and the tbe proposed construction, we recommend spread
fsetings placed on thc undistubed nanral soil designed for an allowable bearing pressure
of 2,000 psf for support of the proposed building. The soils tend to compress when
loaded and thcre could be term foundation settlanrent. Footings should be a
Floor Slabs: The natr.rral on-site soils, exclusive of topsoil, are suitable to support lightiy
loaded slab-on-grade construction. To reduce the effects of some differential movsmenl
floor slabs should be scparated from all bearing walls and colurnns with expansion joints
which allow r:nrestrained vertical moveruert. Floor slab conE-ol joilts should be used to
reduce darnage due to sbrinkage cracking. Tbe requirerrents for joint spacing and slab
reinforcemeDt should be established by the designer based on experience and the intended
slab use. A minimum 4 inch layer of gravel should be placed beneath rhe floor slab for
support and to facilitate drainage. This material should consist of minus 2 inch aggregare
w ith less rhan -s0% passing the No. 4 sieve and less than I 2o,b passing the No. 200 sier c.
Ait fill materials for supporr of t'ioor slabs should be compacted to at ieast 9502'c' of
ma.rimum srandard Proctor density at a moisture content near optimum. Required fiil crn
corrsisr of the on-site soils or suitable imponed granular soils devoid of vegetation, topsoil
and oversized rock.
Surface Drainage: A perimeter foundadon drain around the building should not br
needed due to the slab.at-gade construction. The following drainage precautions shoulii
be observed during constntction and maintained at all times after the building hrs been
completed:
l) Inundation of the foundation excavations and underslab areas should be
avo ided during consEuction.

Percolation Tecting:.,Pedolation tests were conducted on Oaobcr 6, 2005 to evaluate
the fe*ibjlity of au iriniation septic disposal system at the site. Oneprofile pit and three
po*tffi*bii Uoles weri: dug at theiocations shown on Figure l. The teit hotes (nominal
12 inch diamaer by 12 iach deep) wcre hand dug at tbc bottom of shallow backhoe pits
and were sbatea with water one day prior to testiug. The soils exposed in the percolation
holes are similar to those cxposcd in the Profile Pit shown ou Figure 2 and consist of
sandy;.rJty g!ay. The percolation test restrlts, presented in Table 2, indicate percolation
nates rinsSng fiom about 99 1e I $$ minutes per incL Based on the subsnrface conditions
encorrnit#ed and the percolation test results, thc tested area is not zuitable for a
conventional infiluation septic disposal system. A civil englneer should desiga the sentic
disposal systern.
Limitrdons: This study has been conducted in accordurce with generally accepted
geotechnical engineering principles and practices in this area at this time. We male no
warranty either expressed or implied. The conclusions and recommendations submitted
in this r€port are based upon the data obtained from the exploratory pits excavated at t-he
locations indicated on Figwe 1, tlre proposed t1,pe of constuction and our experience in
the area. Our services do not include determining the presence, prevention or possibilitl
of mold or other biological contaminants (MOBC) deveioping in the furure, lf the clieni
is concemed about MOBC, then a professional in this special 6eld of practice should be
consulted. Our findings include interpolation and exuapolation of the subsurface
conditions identified al the exploratory pits and variations in the subsurface conditions
may not become evident until excavation is performed. If conditions encounterd dwing
construction app€ar different from those described in this repor! rve should be notified at
once so re-eva]uation of the recommgndations mav be mrde.
This report has been plepared for the exclusive use by our client for design purposes. \\'*
are not responsible for technical interpretations by others of our information. As the
project evolves, we should prolide continued consultation and field sen'ices dunng
construction to review and monitor the implemcrrtation of our recommendations, and to
veriry that the recommendations havebeen appropriately interpreted. Si-enificant design
changes may require additional analysis or modifications to the recommendations

MAP LEGEND MAP INFORMATION
The soil surveys that comprise your AOI were mapped at
1:24,000.
Waming: Soit Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soils that could have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map
measurements.

Web Soil Survey URL:
Coordinate Sysiem: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on lhe Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.
This product is generated from the USDA-NRCS certified data as
of the version date(s) listed below.
Soil Survey Area: Rifle Area, Colorado, Parts of Garfield and
Mesa Counties
Survey Area Data: Version 16, Au122,2423
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.

The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor
shiftlng of map unit boundaries may be evident.
